Black spots on skin

From the day I got her Miley has had hardly any hair on her ears and lovely pink skin under the little she does have. This past week though ive noticed she is getting black spots on the skin on her ears. It is definitely skin and not hair. Anything to worry about?

Are they raised or flat? Has she been out in the sun? Bug gets flat black spots on her ears and tummy as she has quite fair skin and likes to sunbathe! They're sort of like freckles really..

As far as I can tell they are flat. She only had her second jab on Tuesday so is still only outside when I take her for the toilet so isn't spending more than 5 minutes a few times a day outdoors. She's eating and playing etc as normal so I'm not overly concerned but did wonder if it's something I should keep an eye on with her being mostly white and the vet warning me she is more prone to skin problems and sunburn than dogs of other colours.

My boy has these & they're increasing, i think they're freckles

My parents staff was white when they first got him and about 5 years on his fur is still all white, but he is probably about 40% covered in black spots and patches! He doesn't have any skin problems and the vets have never been worried so I would imagine that it is just pigmentation change as they grow

Well I'm now totally unconcerned about this as the little hair she now has on her ears also has black spots, she is also getting a few come up across her body..I think she's turning into a Dalmatian

I used to put suncream on my white pup
